The invention is also its method of use for assessing fibre-cement board in order to predict the fibre content of the board, to predict the moisture content of the board, or to predict mechanical properties of the board comprising: a source of near infra red radiation; a near-infrared detector for obtaining a near-infrared spectra, the detector being mounted in association with a size roll; and means for predicting the fibre content of the board, the moisture content of the board, or the mechanical properties of the board by reference to the near-infrared spectra obtained. |
